The stiffness of the arm also has a big impact on the feel and how the car uses it's tyres. They might also be making changes to the weight of the arms which would change the feel again. It's gonna be a different beast that's for sure

That's exciting. People are saying they had hoped to see more changes, but the things they've altered are some of the most impactful of all. The no c-hub design is out there, and definitely effective (I love my Awesomatix), but it's not without compromises.

Haven't you heard? Tamiya's gear diff is perfect.

Honestly nobody knows the story on the gear diff yet. If they narrowed the bulkheads, then it might be new because the CAD drawings don't show any overhang in the diff cams like you see with the T4 (so it could retain the same diff as the T3 even with narrower bulkheads.) I think many of us are hopeful for an improved gear diff, but be careful who you mention it to, you might hurt someone's feelings.

The gear diff is seriously fine if you use kyosho orings and better shims, BUT I agree you shouldn't have to do that. I also agree that my best tamiya gear diff is still worse than any xray gear diff.

Regardless, I'm looking forward to seeing this car. I'm a bit suspicious of the translation about the suspension components being different, I think it may just be referring to the use of the shorter shocks from the TB04. Time will tell!

Got tired of it leaking so last resort I did is put a small amount of silicone around where the diff case snap together and walla no lick... I also use kyosho O-ring and X3 0.5 washer on both side...

Here's a slightly different translation than what was on kentech's site. Obviously most of it doesn't make sense since it was translated by a machine.

he victory in the race of many since its debut in 2010, his third consecutive in the 2012 World Championship, TRF417 series achieved world domination for the fifth time. "TRF418" (tentative name) will debut as All Bran new chassis to the world championships to be held in 2014.
The machine even while test and tire power and the latest sources, was designed to take full advantage Jirusu players active world champion Mark player, and Victor player, and feedback from the TRF works driver, almost all new design. The evolving challenges and always, yet the winner, please stay tuned to TRF418 means to challenge the six world championship win of unprecedented!

I wonder why they needed new suspension mounts? It mentions that as one of the changes on kentech's blog. The 1pc mounts don't appear to have a third mounting point (locating pin) like the Yokomo. They look slightly different but that could just be the CAD rendering.

On the CAD pictures you can see that the front split blocks have the edge chamfered. Perhaps needed with the new steering arms and front uprights to avoid the steering links hitting the blocks. It's been close on the current car with some setups. If there are any other changes to the blocks I don't know.

So Wilck beat Hagberg at the Swedish TC nationals. You think that was a 418 vs a T4'14? I looked briefly, and the picture on the SpeedPassion page doesn't look like a 418, but who knows if that's actually the car he was running. See pics at the bottom.
